UNIVERSAL CHANGE MAKER.

To all whom it may comerri:

Be it known that I, Hneo J. BAUR, a citizen of the United States, and a resident of the city of Chicago, in the, county of Cook and State of Illinois, have invented certain new and useful Improvements in a Universal Change Maker; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to "the accompan ing drawings, and 'to the numerals of re erence marked thereon, which form a part ofthis specification.

Many diflerent kinds of changemaking devices are in use on practically all trans portation lines and are a great convenience for the conductor but that which is worn upon the person has been found to be the most practical. The objection heretofore, however, to a change-maker device has been due to the factthat on certain lines of transportation, particularly in the large cities, the denominations of coins received by the conductor from the passengers vary to a large extent and the change making devices havenot been sumciently large to accommodate the predominant denomination of coins received. As a consequence certain of the tubes of the change making devices have been practically empty, whereas others are entirely filled and the surplus coins must be carried in the pocket or some other receptacle. It is not at all unusual that the predominating coins received on one transportation line is a five cent piece and on another a ten cent piece or even coins of greater denomination. Consequently a standard type of change-making device is not well adapted for use upon the different transportation lines.

This invention comprehends what I term a universal change-maker, that is one which may be built up of any desired number of tubes inasmuch as each of the coin tube elements is readily detachable and releasable from the others, and yet when the same are in assembled relation, they are all co-actively connected to be looked as a unit to prevent discharge of coins from any one thereof.

or more tube maybe more than one coin if desired, and by a preliminary adjustment of the parts a predetermined number of coins from any one or more of the tubes may be discharged by single operation of the eject- 111% lever.

lllS is particularly desirable since the recent increase of cash fares above the usual five cent fare, and on many lines the fare now required is six or seven cents.

The inconvenience resulting is due to the fact that chan e of three or tour pennies is required and t e usual cointendered to the conductor is the ten cent piece. With the general type of coin changers now in use, in order to return four pennies to the passenger, necessitates four operations of the ejecting lever by the conductor and consequently where a great number of passengers are received into the car a considerable time and efifort isexpended in making the change where the exact fare is not tendered.

ll overcome these objections to the ordinary type of coin changers in my new universal type of changer by makin it pos sible to vary the number of coins e ected by one operation of the ejecting lever, and as a consequence the three or four pennies in the instance above described may be easily ejected by one operation of the'lever.

It is an object, therefore, of this invention to construct a universal changemaking device wherein the coin receiving and ejecting elements for the respective coins are detachable one from /another and readily assembled in any relation whatsoever, and with an interlocking mechanism on each of the coin elements to prevent ejection of coins therefrom.

It is also an object of this invention to construct a change making device wherein mechanisms are provided for varying the number of coins ejected from a coin tube with one operation of the ejecting lever.

It is also an object of this invention to construct a change making device constituting coin tube elements for diflerent denominations of coins which may be readily assembled one to another in any desired relation or order and each independently operable to eject the coins from a particular tube and with the locking mechanism of each tube element co-acting with those of all the others whereby operation of one ef fects operation of all thereof as a unit.

It is also an object of this invention to construct a change making device wherein a number of coin elements exactly similar in construction may be readily assembled one to another, each having a separate ejecting mechanism which is adaptable to cause ejection of any predetermined number of coins desired by one operation, and each element provided with a locking mechanism to lock the same from operation and with all of said locking mechanisms co-operating to operate as a single unit when said elements are in assembled relation.

It is finally an object of this invention to construct a simple, cheap and durable universal type of change making machine for coins with the parts practically all of stamped metal and with the elements of the device independently operable as a single unit and readily connected to one another to form an assembly of unlimited number of coin elements;

Other and further important objects of this invention will be apparent from the disclosures in the s ecification and drawings.

The invention in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown on the drawings:

The change making device may be built up of any number of coin tube elements, but for convenience of illustration I have shown the same as composed of five receiving elements, one or more thereof as desired, for

certain denominations of coins and with the respective elements denoted as a whole by the reference numerals 1, 2, 3, 4, and 5. Each of said coin tube elements consists of a frame or yoke member substantially of U-shape, as shown in Figures 4 and 9, having upright portions 6 and 7, respectively and an integral connecting top piece 8. The outer or forward edges of this U-shaped member are headed inwardly as denoted by the reference numeral 9 and clearly shown in Figures 4 and 7. At its lower extremity the U-shaped member has its ends bent upwardly and inwardly as denoted by the reference numeral 10, in Figure 9, to support a stationary base plate 11, shown in detail in Figure 15, and provided with tongues 12, which engage through apertures therefor in the side members 6 and 7 of the U-element. An elongated slot 13 is cut in each of said side members 6 and 7, as shown in Figures 10 and 11, with the metal beaded inwardly on the edges of said slot to afford attaching means for a belt or strap by which one or a number of coin tube elements may be carried.

Another plate 14 is attached between the side portions 6and 7 of the U member, said plate 14 having tongues 15, which engage through apertures in said side members simllar to the tongues 12 of the, plate 11 already described. Said plate 14 has attached thereto beneath the same another plate 16, held in assembled relation therewith by a small screw or bolt 17.

Slidably disposed above the plate 11 is an ejecting plate 18, shown in.Figure 14. This plate 18 has a locking notch 19 therethrough and communicating therewith is a long slot- 20. A locking slide bar 21 is attached beneath the plate 11 by screws 22, as shown in Figure 3, and is slotted to permit sliding engagement with said attaching screws. Said plate 4 21 is provided with an upwardly turned locking tongue or lug 23, which projects into the slot 20 of the plate 18, (Fig. 14,) permittinglongitudinal movement of saidplate, but when the locking bar 21 is shifted laterally said tongue 23 engages into the notch 19, thereby locking said plate 18 from longitudinal movement. Each of said locking slide bars 21 is bent downwardly at 8 its ends and these ends are of arc shape, as clearly shown in Figure 3. whereby, when the coin tube elements are in assembled relation, the ends of the respective locking slide bars 21 contact with one another so that movement of either lockin bar 21 of either of the end elements of t e "assembly will cause a coincident movement of all of the locking bars as a single unit. Secured through the plate 18 is a screw 25, the head of which has sliding engagement with a slot 26 provided therefor in the plate 11, as

which are movable with the menace shown in Fi ures 3 and 15, and held attached to said ejecting plate 18 by said screw are other ejecting plates 27, 28 and 29 I res ctively.

e top plate 14 and the bottom plate 11 are always stationary, butany one or more of the four plates together with the slide plate may be movableto eject any number of coins by one operation, as herein fter described. The length of the respecti' e screws 17 and 25 determine the number'of intermediate plates between the plates 18 and 14.

late 18 or stationary withthe plate 14. T e thickness of the respective plates 16, 29, 28, 27 and 18 corresponds to the thickness of the particu lar denomination of coins of the coin element of which these plates form a The screw '11 engages through the plate 14 and the plate 16, whereas the screw 25 engages through the plate 18 as well as plates 2T, .28 and 29, as clearly shown in Figure 11. By changing the respective screws 1? and 25, to those of diderent length, any desired number of plates may be caused to move with theplate 18 for an ejecting operation and the remaining plates .are held stationary with the plate 14.

Each of said plates is provided with a circular coin aperture equal in diameter to aparticular denomination of coin and denoted by the reference numeral 30. The stationary bottom plate 11, however, is merely provided with a semicircular recess 31, which is on the end of said plate and normally out of register with the coin apertures 30 of the other plates, so that when an ejecting operation takes place and the amrtures 30 of the movable plate slide outwardly to register ,with the recem 31, the coins moved outwardly thereby as hereinafter described will fall from the device. Supported upon the top stationary plate 14 is a coin tube 32, having tongues 33, at its lower end which engage in notches provided therefor in said plate 1-1 around the coin aperture 30. As shown in Figure 5, said coin tube is split longitudinally so that the same may be sprung, by pressure on its exterior surface to cause the tongues 33 thereon to engage into the apertures provided therefor in the plate 14, and due to the msiliency of the coin tube element 32 the wine will be tightly engaged with said plate 141. At its upper end, as clearly shown in Figure 5, a notch 3a is provided in the tube element 34, and fitted over the upper end of said tubeis acap 35; having a flanged portion 36,,

which engagesbeneath the top inember 8 of the yoke element, and said cap 35 is provided with two inwardly directed portions 37 and 38, which afiord a coin slotfor intuction of coins into the coin tube. Said cap 35 is provided with an inwardly directedtongue39, to engage with the notch 34}:

part.

of the coin tube, as shown clearly in Figure 11, to lock the cap from rotational adjustmenton the coin tube.

The operating mechanism for causing movement of the assembled ejecting plates is described, in the following: Secured transversely between the side frame members 6 and I, as shown clearly in Figure 9, is a shaft 10. Pivoted adjacent said frame members are depending levers 4:1, with a spacing sleeve 12 therebet-ween on said shaft. Each of the plates 11, LT, 16, 27, 28 and 29 respectively is provided with a cutaway portion 43, on each side thereof, as clearly shown in Figures 12 to 15inclusive, with the exception of plate 18, and the lower ends of said levers 41 engage through the cutaway portions 43, to interfit with notches 44: in the plate 18. Also secured between the side frame members 6 and 7 is another shaft 15, as shown in Figure 9, and pivoted thereon are actuating levers or cranks t6, (see Fig. 10,) one on each side, and each having an upwardly extending crank arm 4:7 provided with a pin 48, which engages in a slot 49 of the respective lever 411., A spacing sleeve 50 is provided on said shaft to between the levers -:t6 and coiled about said sleeve are springs 51, one on each end thereof, one end of each of which, as shown in Figure I, bears downwardly on the top of the stationary plate 1 1, and the other end of each of which is bent around the grooved ends of the pins 48, shown in Figure 9. Said actuating levers 16, are joined by a. cross piece 52, which extends across the front of the coin tube 32, as clearly shown in Figures 2 and 7.

The adjacent side frame members 6 and 7 of a number of coin tube elements assembled with one another, are provided with apertures therethrough to receive small attaching bolts 53, shown in Figure 7, whereby any number of coin tube elementsmay be assembled with one another, and furthermore the same may be strung on a carrying belt passed through the apertures 13, as shown in Figure 11.

The operation is as follows:

The coins according to their particular denominations are deposited in the coin tube elents, either 1, 2, 3, 41, or 5, as the case may be, the coin tube element 1 being designed for dimes, the element 2, for pennies, the elements 3 and '4: for nickels and the element 5' for quarters. Qt course, any number of elements of a particular denomination of coins may be used in the assembly and the bly is not invited to five such elements associated with one another, as I have. shown, but'to any number, more or less than 5 as desired. Each of these elements'is independentlyoperable in so far as the deposit'and ejection of'coins is concerned, but the lochng mechanisms ofall of said elements are oo-active, whereby movement of the locki member into looking position of the en coin tube element serves to operate all of the locking mechanisms to locking position and conversely, release operation upon the locking member at the opposite end ofthe assemb y serves to unlock all of the locking mechanisms of the 'locking bars intermediate" the end elements thus throwing one group into locked or unlocked relation and leavlng the other group in their origi'nalrelation. Thus only one element may be unlocked for operation and all the others locked or one locked and all the others unlocked, or the number of locked and unlocked elements may be varied at will. I

Any predetermined number of coins desired may be ejected from any particular element in one operation by a preliminary adjustment of the parts. As pointed out, at the bottom of the coin tube 32 there is a stationary top plate 14 and a stationary bottom,plate 11 and intermediate thereof are five slidable ejecting plates. The lower Y slidable ejecting plate 18, is capable of eect mg one corn, and each of the other p ates t-hereabove, if locked tp said plate 18 by the screw 25, is also adapted each to eject a quiring coin. In the present instance shown three plates, 27, 28 and 29 .respectively, are shown associated with the bottom plate 18, so that.

there are four coins ejected with each operation ofthe lever 52. This is the proper change for a ten cent piece where the fare on the car is six cents and the coin tube element shown is adapted to receive pennies, so that four pennies are e'ected with each operation of the lever. y changing the length of the respective screws 17 and 25, any number of the four intermediate plates 27, 28, 29 and 16, may be made movable or stationary according to the desired number of coins it is intended to eject.

The method of assembly of the various coin elements or units is entirely simple, reonly the insertion of the small assembly bolts 53, through the apertures pro vided therefor, and then of course the slots '13 in all of said units are substantially registered to 't insertion of acarrying belt therethrough. As clearly shown in Figure 10, all of the plates above the plate 18 are slotted or cut; away to permit the lower end of the levers 41 to swingv relative thereto in moving the slide plate 18,.

provided the plates above the slide plate 18 are stationary and not attached to said plate 18. When the operator depresses the lever 52, the crank arms 47 are pressed forwardly against the stress of the springs 51, and said cranks 47, with their pins 48 in the slots of the levers 41 operate said levers forwardly to move the ejecting plate 18 and other lates associated therewith. When the lockmg bar 21 of the coin element is moved laterally, the tongue 23 on said bar engages in the notch 19 of the slide plate 18 preventing complete movement thereof or consequent movement of any of said ejecting plates to carry the coins outwardly for discharge. Normally .the coins within the coin tube rest upon the bottom plate 11 upon the portion shown in Figure 14, and when the plate 18 is moved outwardly together with any of the other plates attached thereto, the predetermined number of coins are caused to slide outwardly on the plate, 11 until in alignment with the cut-away semi-circular portion 31, they fall.

from the device into the hand of the operator.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necemitated by the prior art.

I claim as my invention:

1. A change maker comprising a plurality of coin receiving and ejecting elements detachably secured together, a' locking mechanism on each of said elements, the operating means of said locking mechanism being so located on each element that when the elements are secured together the said operating means will cooperate to enable all the locking mechanisms to be operated together.

2. A device of the class described comprising a plurality of detachable elements independently operable, and co-active locking mechanisms mounted on each thereof adapted to effect locking of all of said elements by operation of one thereof.

3.
